include menu into all pages except main_1.htm

i am trying to create a conditional statement with TBS, and I am having a very difficult time.

this is my first time using this template system, so any tips is greatly appreciated.

what i want to do is include a specific file (just like include() php function) but in my .html file, and use a conditional if != statement to show the menu in ALL pages except main_1.htm.

does anyone know how to do this or can give me an example to learn from?

If all pages except index.html have the menu then won't they have the same page layout? So use one layout for all those and a separate layout for the one unique index.html without menu.

Otherwise, post the code you're having trouble with so someone here can see what you're doing and offer suggestions.

maybe this will help clarify.

this file called: main_1.htm hosts my header and footer the the entire site. and the contents goes here:

..header code...
    <div id="inner-templates-container">
      <!--[onload;file=[var.inner_template1];getbody;comm]-->
    </div>
..footer code...

i have a file called inner_index.htm - this file acts as my index/default file for the site and i don't want the same header being used as on all other pages and i don't want inner_index.htm to use the header that is called in main_1.htm - the header is different for the homepage.

does this help clarify?
